Abstract

The gross internal anatomy of the cephalocarid crustacean Sandersiella chilenica Stuardo & Vega, 2011 is described based on light microscopy of histological sections of three specimens of the type series, all collected in coastal soft bottoms off central Chile. Observations mainly concern the nervous, digestive, and reproductive systems, heart, haemocoel, and skeletomusculature. The main organ systems and musculature are similar to those previously described for Hutchinsoniella macracantha Sanders, 1955, Lightiella magdalenina Carcupino, Floris, Addis, Castelli & Curini-Galletti, 2006, and Sandersiella sp.
